In the field of industrial communication, Modbus RTU and RS-485 are often mentioned together. Many people mistakenly believe they are the same thing, but in reality, these two concepts are entirely different; they are simply used in close conjunction in industrial control. What is RS-485? RS-485 is a physical layer communication standard that defines how … Read more
Click to follow and stay on track in your learning journey! Last time, we delved into the core elements of the MODBUS protocol. I wonder if you have memorized those key points and successfully established a foothold in the world of MODBUS? If you haven’t fully digested the information yet, make sure to review it … Read more
“Solving the Factory Communication Lag Problem, Improving Equipment Response Speed by 80%! A Deep Dive into Profinet vs. Modbus” (Suspenseful Opening) Hey folks! Today, let’s talk about a problem that drives engineers crazy—suddenly, the equipment in the workshop goes “silent,” and the PLC and HMI are performing a “disconnection drama.” Have you ever experienced that … Read more
Hello everyone, today we are going to discuss a topic that is both frustrating and rewarding in the industrial field—how to make the “old gentleman” Modbus and the “modern youth” TCP/IP shake hands and make peace. Last year, while debugging a sewage treatment plant project, I encountered a “generation gap” issue between these two protocols, … Read more
Introduction **Hello everyone!** Today, I want to talk to you about a frequently overlooked but extremely important part of PLC programming —hardware programming interfaces. “Isn’t it just about plugging in a cable?” **You might think so. But I want to tell you that **choosing the right programming interface can improve your debugging efficiency by over … Read more
